If I'm creating a booking manually/directly through the Uplisting website (as opposed to a guest booking through our website), then the Upsells don't appear on the guest pre-checkin/booking page where they sign Ts&Cs/security deposit etc.

This is even when there are no filters set on the booking, and the upsell is within the configured time window to appear.

I would expect Upsells to appear on the direct booking page either when there are no filters set, or when the "Booking site" filter includes the "Uplisting" option
